||Inventing Jolly Jumpers
Susan Olivia Poole (1889–1975) grew up in Minnesota at the White Earth Indian Reserve. Poole invented the Jolly Jumper, a baby jumper, in 1910, but it was not until 1948 that they were produced for the retail market. By 1957, the Jolly Jumper was patented and became a success with parents everywhere.
